Trains

These games takes their family name from the feature that the players
build their own private trains instead of playing on a shared layout for
the initial part of the game.

The goal is to domino, since scores are based on the tiles left in the
other players hands.

This family is usually played with a larger domino set, say double nine
or double twelve, but it is possible to play them with a double nine or
double six set for a faster game. A smaller set and fewer players is not
as good a game, however. You would need to adjust the size of the hands
according.

Given a double twelve set, you can make smaller non-traditional sets to
adjust the games to either less time or a smaller number of players. If
you decide to build a smaller set, you should consider the problem of
whether or not a single train exists, since it will affect the game.
